I am trying to install Windows 8 Pro using UEFI and GPT, however, despite being able to boot the installation disc using UEFI, I am unable to get past the "Copying Windows files (0%)" phase. It either freezes and accepts no mouse input, or BSOD's after a while with the message "CLOCK_WATCHDOG_TIMEOUT". If it means anything when I run a CHKDSK on the X: partition created from the disc it fails with 7 errors, and apparently the specific BSOD I mentioned can be caused by a corrupted disc. Does anyone have a solution to this problem, or do I have to request a new disc from PC Specialist? Thanks.
